Preview crashed with multiple files open not will not open
Preview recently crashed with multiple large files in Preview on my Macbook Pro Retina (2012). I was really taxing the system, copying files from photoshop, when it initially crashed. Now the app crashes when opening every time. The app attempts to reopen all the files that were open at initial crash. Is there any way to reset the app? I don't think there is a way to reinstall Preview without a reinstall of the OS, or is there?
Thanks a million
MacBook Pro with Retina display, OS X Yosemite (10.10.2)
